I have just purchased the Tab S7+ 256gb now that it's available in the UK. It arrived pre-loaded with the latest OneUI 3.1.
I've noticed that with a Bluetooth Mouse connected, and within Dex mode you cannot left-click within browsers. It does seem to work perfectly fine outside of Dex mode and it does also work perfectly fine with the keyboard case.
The mice I've tested are the Logitech MX Master 3 and the Logitech MX Anywhere 2.
Both mice work perfectly fine with my Samsng Tab S6.
Has anyone else with a Tab S7 or S7+ with either the 256gb or 128gb model exeprienced this (with or without the latest update?)
I've raised a support ticket with Samsung Support and they say they're raising it to their product specialist team as a bug in Dex, but I don't know what traction this will raise if I'm the only one who's noticed it.
